Modeling is an essential part of simulation and implementation of control and observation techniques; therefore the model adopted should be interpreted as accurately as possible such that it captures all the phenomena that the designer seek for; which are very important to predict the transient and steady-state physical systems. In this book modeling of each machine is introduced in a simple way as well as their simulation using Matlab, Simulink that gives clear insight on how to use Matlab for modeling; then a vector field control is introduced in details with their simulation using Matlab/smulink as well.

This book introduces electrical machine modeling and control for electrical engineering and science to graduate, undergraduate students as well as researchers, who are working on modeling and control of electrical machines. It targets electrical engineering students who have no time to derive mathematical equations for electrical machines in particular induction machine (IM) and doubly fed induction machines (DFIM). The main focus is on the application of field oriented control technique to induction motor (IM) and doubly fed induction motor (DFIM) in details, and since the induction motors have many drawback using this technique, therefore the application of a nonlinear control technique (feedback linearization) is applied to a reduced order model of DFIM to enhance the performance of doubly fed induction motor. Features Serves as text book for electrical motor modeling, simulation and control; especially modeling of induction motor and doubly fed induction motor using different frame of references. Vector control (field oriented control) is given in more detailed, and is applied to induction motor. A nonlinear controller is applied to a reduced model of an doubly induction motor associated with a linear observer to estimate the unmeasured load torque, which is used to enhance the performance of the vector control to doubly fed induction motor. Access to the full MATLAB/SIMULINK blocks for simulation and control.

About The Book: MATLAB is widely used in universities and colleges for graduate studies and research. Recently, MATLAB is being introduced to undergraduate students. Most of the books available on MATLAB are focused mainly on its use as programming language. The objective of this book is to explore the role and possibility of MATLAB, Simulink and its toolboxes in electrical and electronics engineering curriculum to promote modeling, simulation and virtual experimentation with emphasis on analysis, design and simulation study. The use of MATLAB needs that the user should know the concepts, fundamental and theoretical framework required to obtain the solution. Therefore, the author prefers to suggest the use of MATLAB as an equation solver tool from students learning and understanding point of view.

With its comprehensive coverage of the state of the art, this Second Edition introduces basic types of transformers and electric machines. Classifications and characterization—modeling and performance—of power electric transformers (single and multiphase), motors and generators, commercial machines (dc brush, induction dc excited synchronous, PM synchronous, reluctance synchronous) and some new ones (multiphase ac machines, switched reluctance machines) with great potential for industry with rotary or linear motion are all treated in the book. The book covers, in detail, circuit modeling characteristics and performance characteristics under steady state, testing techniques and preliminary electromagnetic-thermic dimensioning with lots of solved numerical examples and special cases to illustrate new electric machines with strong industrialization potential. All formulae used to characterize parameters and performance may be safely used in industry for preliminary designs and have been applied in the book through numerical solved examples of industrial interest. Numerous computer simulation programs in MATLAB® and Simulink® that illustrate performance characteristics present in the chapters are included and many be used as homework to facilitate a deeper understanding of fundamental issues. This book is intended for a first-semester course covering electric transformers, rotary and linear machines, steady-state modeling and performance computation, preliminary dimensioning, and testing standardized and innovative techniques. The textbook may be used by R&D engineers in industry as all machine parameters and characteristics are calculated by ready-to-use industrial design mathematical expressions.

Not only do modeling and simulation help provide a better understanding of how real-world systems function, they also enable us to predict system behavior before a system is actually built and analyze systems accurately under varying operating conditions. Modeling and Simulation of Systems Using MATLAB® and Simulink® provides comprehensive, state-of-the-art coverage of all the important aspects of modeling and simulating both physical and conceptual systems. Various real-life examples show how simulation plays a key role in understanding real-world systems. The author also explains how to effectively use MATLAB and Simulink software to successfully apply the modeling and simulation techniques presented. After introducing the underlying philosophy of systems, the book offers step-by-step procedures for modeling different types of systems using modeling techniques, such as the graph-theoretic approach, interpretive structural modeling, and system dynamics modeling. It then explores how simulation evolved from pre-computer days into the current science of today. The text also presents modern soft computing techniques, including artificial neural networks, fuzzy systems, and genetic algorithms, for modeling and simulating complex and nonlinear systems. The final chapter addresses discrete systems modeling. Preparing both undergraduate and graduate students for advanced modeling and simulation courses, this text helps them carry out effective simulation studies. In addition, graduate students should be able to comprehend and conduct simulation research after completing this book.
